One common name for this tree is "Tulip Poplar." However, it is not in the poplar family, but in the magnolia.

Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. A cultivar is a named variety of a particular plant that was selected or breed to have certain characteristics, often they’re vegetatively propagated  so all the plants with that name are exactly the same. It used to be that people often planted seedling dogwoods in their yards and the only downside was perhaps waiting a long time for the trees to bloom.

Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. The dreaded Dogwood anthracnose, Discula distructiva, is a death knoll for that loveliest of native trees. There is another disease called spot anthracnose caused by a different fungus that fortunately is cosmetic instead of fatal. It causes problems when we have a wet spring with high humidity and may just make small lesions on the leaves that you probably won’t even notice it.

Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. Dogwood anthracnose, with the frightening name Discula distructiva, was first identified in north eastern forests in 1978. Beginning with attacks on leaves and twigs, this disease spreads to branches and trunks and has caused mortality rates well above fifty percent in the Great Smoky Mountains National Park.

Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. Riding up to Clemson recently, my husband and I couldn’t stop ohhing and ahhing about the beauty our native flowering dogwood, Cornus florida, in full bloom, gave to the woodlands bordering the highway. Dogwoods are naturally an understory small tree, occurring in open woods or along their margins.

Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. If you visit the website Charlotte Tree Plan and read about the benefits of urban trees you’ll be encouraged to plant the largest shade tree possible in your yard this fall. For us, fall is the best time to add new trees and shrubs to our landscape, the roots can grow during the winter making the plant stronger when next summer’s hot weather rolls around.  At the Charlotte Tree Plan page, you’ll see the many benefits residents of the Queen City receive from their urban forest.

Inchworms a Threat?

Sep 7, 2017

Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. We enjoyed the solar eclipse from the comfort of our Saint Matthews yard. Although lots of people searched out and set up camp in open fields, I’m not a sun lover and we simply  made periodic forays from our  covered porch out into an  open area of the front yard to observe the progress of the blackout. Numerous shade trees help keep our eighteen eighties home cool, a  value familiar to residents of cities with active urban tree programs.

Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. Making It Grow gets lots of calls from Charlotte, right up the road in North Carolina. Charlotte is rightfully proud of its urban tree program and the City does a lot to protect its valuable tree canopy, which provides numerous benefits to its citizens. As we watch the devastation from Hurricane Harvey, it should serve as an encouragement for all of us to plant trees in our urban areas.

The Silver Maple Tree's seeds have samaras, "wings" that help the seeds travel on the wind.

When you bring your Christmas tree in from the outdoors you may find some hidden hitchhikers.

Post Oaks

Dec 22, 2016

Hello Gardeners, I’m Amanda McNulty with Clemson extension and Making It Grow. There are two magnificent post oaks, Quercus stellata, growing in the yard of an abandoned house in St. Matthews that I admire for their incredible character.  Post oaks are in the white oak family but have their own distinctive appearance as they are gnarly, open in habit, with twisted branches.

Happy Arbor Day!

The date for Arbor Day varies across climate zones.

Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. The US Department of Agriculture’s Natural Resources Conservation Service has fact sheets that give detailed and fascinating information about native plants. An extremely comprehensive resource, it begins with a thorough description of the entire plant. Most interesting to me is the history of its uses by native people and others for medicinal and utilitarian purposes.

A transplant from Oklahoma/Arkansas/Texas, this tree, though not common in South Carolina, can sometimes be found around 19th century home sites. 


Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. Plant snobs, yes, even the kindest and sweetest of gardeners have their moments of human frailty, often complain about people who prune their boxwoods and hollies into “little green meatballs.”  This practice is harmful as it requires a constant battle against the natural shape of those species. If only these persons would consider planting some of the “globular” cultivars of Thuja occidentalis. This native tree which reaches forty feet or more in nature has been tweaked by plant breeders and now comes in such wonderfully named cultivars as “Mr. Bowling Ball. Hetz Midget is a light green ball-shape of the same size. Thujas  naturally assume a globe or pyramid shape which is attractive and, if properly selected for mature size, require little pruning. In South Carolina, sadly, their use is limited by the fact that deer absolutely adore them. 


Eastern Red Cedars

Jan 4, 2016

  Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. Common names are really confusing when we start to talk about cedars. In South Carolina, Eastern red cedar used to be the ”go to Christmas tree”, despite the fact that they are prickly as the devil. Their leaves are tightly clasped scales when mature (the even more prickly juvenile plants have needles) – –Their scientific name is juniperus virginiana. Red cedars grow in 37 states and are resistant to drought, cold, disease, and just about everything else. They also have great value to wildlife for both shelter andx food., Sadly, they’ve fallen out of favor and people plant Leyland Cypress instead – a tree unsuited to the south and prone to all sorts of deadly diseases. Cedrus is the genus considered the true cedars native to the middle and far east, And are the the cedars referred to in ancient writings, including the Bible.


Shademaster Honey Locust

  Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. Since we southerners are so interested in family names, let’s examine the history of the name for SHADEMASTER honey LOCUST Gleditsia triacanthos var. inermis 'Shademaster' . The genus name, Gleditsia, honors the German botanist of the 18th century named Gottlieb Gleditsch. Now the fun begins – triacanthos means “three spines” referring to the spines that grow out of the trunks of most honeylocust trees.

Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. My favorite professor at Clemson, Dr. David Bradshaw, told wonderful stories about his grandfather who was a true naturalist just from living a life so connected to the land and knowing so many uses for the plants and animals found near his home. When we studied honeylocust, gleditsia triacanthos, David told us that the sweet substance found lining the pods that gives rise to the honey part of the common name had such a high sugar content that his grandfather used it to make beer.

  Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. If you’re in one of the great swampy areas in South Carolina and the water starts to rise or a feral hog is chasing you, for the love of Pete do not climb a Gleditsia aquatica, or swamp locust. Dr. John Nelson recently brought photographs of this tree, found in wet places in the SE as well as his back yard, to the show for a mystery plant. It has clusters of fierce, sharp, long spines growing out of the trunk and would be impossible to safely climb.

If you cut your own Christmas tree, be careful--there may be "packages" in the tree!
